High Voltage Electrician – 8154

June 2010


To troubleshoot, repair, install and service medium and high voltage electrical systems and associated equipment; to operate, inspect and perform preventive maintenance on medium and high voltage overhead and underground distribution systems; to prepare estimates; and plan and manage own projects within allotted budgets; .and to perform related  work required.


High Voltage Electrician is a full journey level classification performing skilled high voltage electrical work in accordance with the techniques of the trade, based on completion of a recognized apprenticeship or its equivalent. This classification is distinguished from other classifications which may perform limited elements of electrical work by its focus on voltage systems above 480 volts and equipment, and by the scope of work and level of skill required. Positions at this level may direct the work of less skilled helpers on projects, and train apprentices; and may work independently or in conjunction with other crafts


The following duties are intended to illustrate examples of duties typically performed by incumbents in this classification. Individual incumbents may not perform all of the duties listed, nor are all of the duties an incumbent will perform necessarily listed.

  • Troubleshoots and repairs overhead and underground distribution systems, including transformers, circuit interrupters, reclosers, capacitors: voltage regulators, medium voltage switches, utility poles, and supporting hardware;
  • Replaces and installs medium voltage overhead and underground electrical circuits and terminations;
  • Fabricates and installs a variety of components including but not limited to duct banks; cable runs, concrete pads for electrical equipment, risers, transformer banks, and low voltage electrical panels;
  • Operates various components on the medium and high voltage distribution electrical system including isolation switches, interrupters, capacitor banks, transformers, overhead fused cutouts, and voltage regulators; isolates and clears sections of the system for maintenance, installation and load shedding;
  • Inspects overhead and underground distribution systems, tests, and documents findings;
  • Responds to emergency calls and takes necessary actions;
  • Provides support for in house capital and in-house projects with commissioning, testing and inspecting finished work;
  • Uses personal protective gear such as hot sticks, respiratory protection, and places or erects clearance tags, barricades, warning signs and devices to protect others;
  • Directs the work of unskilled and semi-skilled helpers assisting in projects, assuring that proper safety practices are followed;
  • Provides on the job training to apprentices;
  • Operates a variety of testing, calibration and repair devices, tools and equipment including voltmeters, ammeters, ohmmeters, insulation resistance testers, high potential test sets, circuit breaker testers, etc.;
  • Coordinates work with customers, project managers, other crafts, and inspectors; inspects job sites and reviews detailed plans, drawings and oral directions to plan work;
  • Prepares detailed estimates including labor and materials, and prepares lists of materials;
  • Assists other crafts as needed;
  • Maintains tools and equipment;
  • Maintains current knowledge of equipment and materials through self-study and training;
  • Prepares and maintains a variety of records and paperwork regarding work

Under supervision, incumbents serve as work leaders for high voltage crews and helpers assigned to a specific job. Incumbents typically transmit and explain work orders; may make minor changes in material needs or modifications to assigned work due to material delays or other problems; communicate work order revisions, material delays or other problems to· supervisor and await further instruction; maintain time and material records; and perform the full range of duties as outlined in the series concept. Additionally, incumbents may have limited responsibilities for making or modifying daily work assignments and for evaluating personnel.
